         of capital stock of the Corporation, and whether or in what
         circumstances such dividends shall be cumulative;

                 (3)      The right, if any, of the holders of such series of
         Preferred Stock to convert the same into, or exchange the same for,

         preferential dividends on any series of Preferred Stock (fixed in
         accordance with the provisions of Paragraph B of this Article V), if
         any, shall have been satisfied and after the Corporation shall have
         complied with all the requirements, if any, with respect to redemption
         of, or the setting aside of sums as sinking funds or redemption or
         purchase accounts with respect to, any series of Preferred Stock
         (fixed in accordance with the provisions of Paragraph B of this page
         Article V), and subject further to any other conditions that may be
         fixed in accordance with the provisions of Paragraph B of this Article
         V, then and not otherwise the holders of Common Stock shall be
         entitled to receive such dividends as may be declared from time to
         time by the Board.

                 (2)      In the event of the voluntary or involuntary
         liquidation, dissolution or winding-up of the Corporation, after
         distribution in full of the preferential amounts, if any (fixed in
         accordance with the provisions of Paragraph B of this Article V), to
         be distributed to the holders of Preferred Stock by reason thereof,
         the holders of Common Stock shall, subject to the additional rights,
         if any (fixed in accordance with the provisions of Paragraph B of this
         Article V), of the holders of any outstanding shares of Preferred
         Stock, be entitled to receive all of the remaining assets of the
         Corporation, tangible and intangible, of whatever





                                       6
   7
         kind available for distribution to stockholders ratably in proportion
         to the number of shares of Common Stock held by them respectively.

                 (3)      Except as may otherwise be required by law, and
         subject to the provisions of such resolution or resolutions as may be
         adopted by the Board pursuant to Paragraph B of this Article V
         granting the holders of one or more series of Preferred Stock
         exclusive voting powers with respect to any matter, each holder of
         Common Stock shall have one vote in respect of each share of Common
         Stock held on all matters voted upon by the stockholders.

                 (4)      The authorized amount of shares of Common Stock and
         of Preferred Stock may, without a class or series vote, be increased
         or decreased from time to time by the affirmative vote of the holders
         of a majority of the combined voting power of the then-outstanding
         shares of Voting Stock, voting together as a single class.


                 D.       No stockholder of the Corporation shall by reason of
his holding shares of any class or series of stock of the Corporation have any
preemptive or preferential right to purchase, acquire, subscribe for or
otherwise receive any additional, unissued or treasury shares (whether now or
hereafter acquired) of any class or series of stock of the Corporation now or
hereafter to be authorized, or any notes, debentures, bonds or other securities
convertible into or carrying any right, option or warrant to purchase, acquire,
subscribe for or otherwise receive shares of any class or series of stock of
the Corporation now or hereafter to be authorized, whether or not the issuance
of any such shares, or such notes, debentures, bonds or other securities, would
adversely affect the dividends or voting or other rights of such stockholder,
and the Board may issue or authorize the issuance of shares of any class or
series of stock of the Corporation, or any notes, debentures, bonds or other
securities convertible into or carrying rights, options or warrants to
purchase, acquire, subscribe for or otherwise receive shares of any class or
series of stock of the Corporation, without offering any such shares of any
such class, either in whole or in part, to the existing stockholders of any
class.

                 E.       Cumulative voting of shares of any class or series of
capital stock of the Corporation having voting rights is not permitted.

                                   ARTICLE VI

                             Election of Directors

                 A.       The business and affairs of the Corporation shall be
conducted and managed by, or under the direction of, the Board.  Except as
otherwise provided for or fixed pursuant to the provisions of Article V of this
Certificate of Incorporation relating to the rights of the holders of any one
or more series of Preferred Stock to elect additional directors, the total
number of directors constituting the entire Board shall be not less than three
nor more than eleven, with the then-authorized number of directors being fixed
from time to time by or pursuant to a resolution passed by the Board.





                                       7
   8
                 B.       On and after the Public Status Date, the Board, other
than those directors elected by the holders of any series of Preferred Stock as
provided for or fixed pursuant to the provisions of Article V of this
Certificate of Incorporation, shall be divided into three classes, Class I,
Class II and Class III, and the Board, by resolution or resolutions adopted on
or prior to the Public Status Date, shall designate the directors who shall
first serve in Class I, Class II and Class III, effective as of the Public
Status Date.  Such classes shall be as nearly equal in number as possible.
Each director shall serve for a term ending on the third annual meeting
following the annual meeting at which such director was elected; provided,
however, that the directors first designated to Class I shall serve for a term
expiring at the annual meeting next following the date of their designation as
Class I Directors, the directors first designated to Class II shall serve for a
term expiring at the second annual meeting next following the date of their
designation as Class II Directors, and the directors first designated to Class
III shall serve for a term expiring at the third annual meeting next following
the date of their designation as Class III Directors.  At each annual election
of directors, the directors chosen to succeed those whose terms then expire
shall be of the same class as the directors of the Corporation they succeed,
unless, by reason of any intervening changes in the authorized number of
directors, the Board of Directors shall designate one or more directorships
whose term then expires as directorships of another class in order more nearly
to achieve equality of number of directors among the classes.  In the event of
any change in the authorized number of Directors of the Corporation, each
Director of the Corporation then continuing to serve as such shall nevertheless
continue as a Director of the class of which he is a member until the
expiration of his current term, or his prior death, resignation or removal.

                 C.       Except as otherwise provided for or fixed pursuant to
the provisions of Article V of this Certificate of Incorporation relating to
the rights of the holders of any series of Preferred Stock to elect additional
directors, and subject to the provisions hereof, newly created directorships
resulting from any increase in the authorized number of directors, and any
vacancies on the Board resulting from death, resignation, disqualification,
removal, or other cause, may be filled only by the affirmative vote of a
majority of the remaining directors then in office, even though less than a
quorum of the Board.  Any director elected in accordance with the preceding
sentence shall hold office for the remainder of the full term of the class of
directors in which the new directorship was created or in which the vacancy
occurred, and until such director's successor shall have been duly elected and
qualified, subject to his earlier death, disqualification, resignation or
removal.  Except as otherwise provided pursuant to Article V of this
Certificate of Incorporation relating to additional directors elected by the
holders of one or more series of Preferred Stock, no decrease in the number of
directors constituting the Board shall shorten the term of any incumbent
director.

                 D.       During any period when the holders of any series of
Preferred Stock have the right to elect additional directors as provided for or
fixed pursuant to the provisions of Article V of this Certificate of
Incorporation, then upon commencement and for the duration of the period during
which such right continues (i) the then otherwise total authorized number of
directors of the Corporation shall automatically be increased by such specified
number of directors, and the holders of such Preferred Stock shall be entitled
to elect the additional directors so provided for or fixed pursuant to said
provisions, and (ii) each such additional director shall serve until such
director's





                                       8
   9
successor shall have been duly elected and qualified, or until such director's
right to hold such office terminates pursuant to said provisions, whichever
occurs earlier, subject to his earlier death, disqualification, resignation or
removal.  Except as otherwise provided by the Board in the resolution or
resolutions establishing such series, whenever the holders of any series of
Preferred Stock having such right to elect additional directors are divested of
such right pursuant to the provisions of such stock, the terms of office of all
such additional directors elected by the holders of such stock, or elected to
fill any vacancies resulting from the death, resignation, disqualification or
removal of such additional directors, shall forthwith terminate and the total
and authorized number of directors of the Corporation shall be reduced
accordingly.

                 E.       Except for such additional directors, if any, as are
elected by the holders of any series of Preferred Stock as provided for or
fixed pursuant to the provisions of Article V of this Certificate of
Incorporation, any director may be removed from office only for cause and only
by the affirmative vote of the holders of 75% or more of the combined voting
power of the then-outstanding shares of Voting Stock at a meeting of
stockholders called for that purpose, voting together as a single class.

                                  ARTICLE VII

                            Meetings of Stockholders

                 A.       Meetings of stockholders of the Corporation may be
held within or without the State of Delaware, as the By-laws of the Corporation
may provide.  Except as otherwise provided for or fixed pursuant to the
provisions of Article V of this Certificate of Incorporation relating to the
rights of the holders of any series of Preferred Stock, special meetings of
stockholders of the Corporation may be called only by the Chairman of the
Board, the President or the Board pursuant to a resolution adopted by a
majority of the then-authorized number of directors of the Corporation;
provided, however, that on and after the Public Status Date, where such special
meeting of stockholders is called for the purpose of acting upon a proposal
made by or on behalf of a Related Person or, at any time that one or more
Related Persons exist, by or at the request of a director who is not a

Continuing Directors, if any, shall also be required to call such special
meeting of stockholders.  Special meetings of stockholders may not be called by
any other person or persons or in any other manner.  Elections of directors

provisions of Article V of this Certificate of Incorporation relating to the
rights of the holders of any series of Preferred Stock, no action required to

of the Corporation may be taken without a meeting, and the power of the
stockholders of the Corporation to consent in writing, without a meeting, to
the taking of any action is specifically denied, provided, however, that prior
to the Public Status date stockholders may take action on any matter by written
consent of all the holders of Voting Stock entitled to vote on such matters.

duty as a director, except to the extent such exemption from liability or
limitation thereof is not permitted under the General Corporation Law as the
same exists or may hereafter be amended.  Any repeal or modification of the
foregoing paragraph shall not adversely affect any right or protection of a
director of the Corporation existing hereunder with respect to any act or
omission occurring prior to such repeal or modification.

                                   ARTICLE X
